  1. Repost? on Using gzip As A Spam Filter · · Score: 4, Interesting
    This post looks like it came from my previous reply on a way to detect entropy (non-repititious content)in P2P files

    Here is a code snippet from the comment:

    #!/bin/bash
    # Entropic analysis by Full Decent
    SIZE=$(cat $1 | wc -c).0
    CSIZE=$(gzip -c --best $1 | wc -c).0
    ENTROPY=$(echo "scale=4; $CSIZE / $SIZE * 100" | bc)
    echo "$1 is ${ENTROPY}% entropic"

    What is Apache Ant? Ant is a Java-based build tool. In theory, it is kind of like Make, without Make's wrinkles and with the full portability of pure Java code.

  3. The solution, but no marketing on Sony: Case of Right vs Left Hand · · Score: 1
    Minidisc was the solution to all the RI problems we've been having.

    I bought one of these things (the MD pkg 5) with a deck and portable player. It featured the ability to copy CD to MD but not CD to MD to MD. And the media was cheap $9 for a disc when CD's were $17.

    Problem is: they never marketed it, ever. I saw like 2 magazine ads and that's it. Even now, when someone sees my MD player, they're like "what's that", "minidisc" "what's minidisc". So the solution was there, then they never marketed it, and noone bought it and the prices rose.

  4. Technical Specifics on Mission: Infiltrate the P2P Network · · Score: 1
    I've found one of the techniques used for reducing quality of mp3's used on P2P, outlined an experiment to test it and provided a solution to fix P2P.

    MP3's are being distributed with "wasteful" bit rates. And by this I mean that a file distrubuted [infiltrated] at 192 kbps has the same entropy as a real file encoded at 128 kbps. They are encoding the files with 128 kbps and putting in junk to raise the file size to 192. This makes the users think they're getting 192kbps files and wasted their download time for the junk data.

    For an example of this, download Thug Mansion with URN:SHA1 = a5f395c8b4148075728dcd79021dd46a083ec425. And compare it to a real one encoded at 128 and a real one at 192 (by real I mean rip your store-bought CD). You will notice that the one with my URN sounds exactly like the 128kbps one.

    A proposition against my theory might be that the encoder was simply low quality. To that, I say: an encoder set at 192kbps would sound better than this.

    A solution to this specific problem is to have users rate files (already implemented), or come up with a technique to determine the entropy of a media file. Apparently they're going to be doing this for movies as well, so a way to check for entropy in videos would be needed soon. This will also handle the songs they put out which are just the chorus played over and over.

    An idea to implement this would be similar to this bash script:

    #!/bin/bash
    # Entropic analysis by Full Decent
    SIZE=$(cat $1 | wc -c).0
    CSIZE=$(gzip -c --best $1 | wc -c).0
    ENTROPY=$(echo "scale=4; $CSIZE / $SIZE * 100" | bc)
    echo "$1 is ${ENTROPY}% entropic"
    This is almost the biscuit. You would have to run this entropy script on the decoded mp3's to determine their true entropy. This is beause the mp3's themselves are compressed (entropic).

  7. The Patent on SBC Demands Royalties for Links in Frames · · Score: 2, Interesting
    Here is the original abstract of the patent:
    A structured document browser includes a constant user interface for displaying and viewing sections of a document that is [sic] organized according to a pre-defined structure. The structured document browser displays documents that have been marked with embedded codes that specify the structure of the document. The tags are mapped to correspond to a set of icons. When the icon is selected while browsing a document, the browser will display the section of the structure corresponding to the icon selected, while preserving the constant user interface.
    Here is a re-interpretation of the same information:
    A [web browser] [works]. The [web browser] displays [HTML documents]. The [HTML] [uses IMG tags nested in A tags]. When [clicked], [the web browser] will [follow the link] [according to the TARGET property of the A tag].

    That's what they want! If you start accepting the DRM and use your hardware to pirate the music. Then DRM will have the argument that "the only thing allowing piracy is compromisable hardware".

    By AOL free area, I meant to say "local sponsored content". Something where they provide local news feeds from popular sources, behind the firewall so they don't have to pay for you accessing it (from bandwith costs).

  17. Re:Local Mirrors on AT&T/Comcast Consider Aussie-Style Bandwidth Caps · · Score: 1
    That is a good point. Consider this situation. If cable companies uncapped end user modems (which would no longer have an affect) and implemented extranet capping, there could be some serious advantages.

    Setting your gnutella client to "prefer local nodes" would give you a 1000% increase in downloaded media transfers, while preventing network poisoning. They could greatly incentivize this by providing mirors for popular archives behind the firewall.

    Imagine an ibiblio or sourceforge mirror behind the firewall downloading at an uncapped speed! That would be enough to shut me the fuck up.

    I'm one of those people comcast called individually to tell me to "stop using bandwith you nerd, the neighbors are complaining". But the ammount of content I access that isn't popular and solvable with this (web caching, linuxiso mirror, sf mirror and local node gnutella) is probabily just several gigabytes a month. And those 5-10 gigs are probabily just porn.

    Comcast keepp trying to push their proxy web servers on customers. Web proxies can greatly reduce bandwith for an ISP, just think of how many slashdot front pages you read that everyone else is too. But companies should incentivize users to make use of proxy services and localize content so that they can save.

    The problem here, is it would look too commercial from the outside and they would abuse it. They would start saying "look at our news sites and it will be like an AOL 'free' area". And we all know what AOL is like.

  19. Morals vs. the Law on Doing Open-Source Development, Anonymously? · · Score: 3, Interesting
    If you violate the contractual agreements in a way where your rights are not explicitly protected by the law. Then you are breaking the law.

    Having anonymous releases is fine, not letting your employer know that you are a more valuable coder than they can tell is your own fault. But deciding to break the agreement you signed is not something you can do because you feel like it.

    You *should* speak with a lawyer and have your contract revised if the contract is in voilation with current laws. Asking your boss to revise their illegal/voided contract is more noble than considering yourself too righteous to acknowledge it. If your lawyer fires you because he though the contract had more value than it legally did, then you could be riding on free paychecks and a new wardrobe.

  25. Re:They pulled the same stunt with IE on Passport for Linux On the Way · · Score: 1
    If you'll recall, the Microsoft products for alternate operating systems have actually been better than the Windows ones. Microsoft actually says this in a press release, I lost the URL, but here are some clear examples (sorry, only Mac ones here):

    * Office 1998 for Macintosh supports translucent contextual menus. This is application-based screen polling and rendering, something you know a programmer would only do if they were in a over-budgeted and over-staffed team with lots of free time and free coffee.

    * MSIE 5.0 for MasOS 8+ has so many more freatures that will never be included in the Windows counterpart: auction tracker, page holder, download manager...

    I think MS is clearly putting a lot of time and money into the alternate operating system development project, and they're making better products than before. So they're making money and the user get products that have been developed (for Windows) and then re-developed (with feature plus) for them. So everybody wins.

    This theory suffices even without the larger picture of adoption and abandonment, so I think the simplest theory is the most probably.
